You can perform a factory reset to clear any errors.
A factory reset sets all configuration parameters to default values. The reset button is located on the back of the base station:
Base station is connected to the power supply or PoE.
1 Press and hold the reset button with a pointed object for several seconds.
After approx. 3 seconds, the LED starts flashing blue at short intervals.
2 Press and hold the reset button for another 5 seconds until the LED flashes blue at longer intervals, then release it.
The configuration parameters are reset.
3 When the LED is solid yellow, disconnect the base station from the power supply and turn it back on after a few seconds.
The base station is restarted.
